Alright then, what's the problem or question you need help on?

For turning decimals into fractions-
put the decimal in a fraction over 1 such as
.75/1
Times that by one hundred
.75/1 x100= 75/100
Simplify down if you have to
75/100=3/4
I hope that helped, I tried doing it as quickly as I can because I'm running out of time >,<

um.... well i'm in algebra 2 and from what i remember: each place after a decimal adds a zero. so like 0.1 would be 1/10 and 0.01 would be 1/100, 0.001 would be 1/1000 and so on. and then if it's even you simplify. hope this helps!

O.o That was fast... Er... I need help on:

0.91


-0.666....

0.525

13.006

17.875

7.75

-8.26

-4.12

Well the way my Pre-Algebra teacher tought me was, if you're multiplying by 100 & the # is .75 then for every space after the 1st # you move the decimal point:
1(00)
.75
7.5
75.
so it makes 75 (a whole #)
so 75/100 = 3/4
Either that or it was simalar to that.. :3

so the for the first one put the 91 over 100 so it's 91/100

the repeating decimals you usually just have to memorize, 0.33333333.... is 1/3, 0.666666.... is 2/3

the third one you would put it over 1000 since there are 3 numerals after the decimal-- 525/1000 and simplify

i think that should be enough for you to get the rest.
